SAMPLE WEIGHT CALCULATOR
To calculate your optimal sample weights, enter %N and %C values for your sample material in
the blue cells. Calculated results are shown in the green cells. See table for examples of %N and
%C values for various materials. Samples must not exceed either 75mg total weight or 12mg of
carbon. Enriched sample weights should be optimized for 20 ug N, with a maximum of 100
ug N (i.e. use the "Smallest sample weight" to "Optimal sample weight" as your target range).
